Highlight the area corresponding to the feature

Enclose the base sequence region corresponding to the feature in a rectangle

  • Turn on the Rect button in the toolbox to enclose the sequence region corresponding to the feature in a rectangle.
  • At this time, the changeable start codon on the base sequence changes to a highlighted display instead of a rectangular display.

Shaded display of the entire area corresponding to the feature

  • Select the All button in the toolbox to shade the area corresponding to the feature.
  • The shaded color is a transparent version of the color assigned to the feature key.
  • At this time, the changeable start codon on the base sequence is surrounded by a rectangle.

Change feature display color

  • If you turn on the FK color button in the toolbox, it will be drawn in the color assigned to that feature key.
    • How to set the FK color.
  • If you turn on the CT color button in the toolbox, it will be displayed in the category color registered for that feature.
  • Category colors are set for each annotation progress stage.
    • How to set the category color.

Insert a blank character every 10bp of the base sequence

  • When the 10Base button in the toolbox is turned on, a blank is inserted in the base sequence display for 10 bases.
  • This is a display only, no blanks are inserted in the actual sequence data.

Operations that can be performed on the base sequence

Changed the start codon position of the CDS feature

If you want to change the start codon position of the displayed CDS feature to another codon, do the following:
